Cabling Considerations
The illustrations in this section display cabling configuration examples that show
the stack bandwidth and possible stack partitioning.
Figure 3-2
shows an example of a stack of Catalyst 3750 switches that provides
full bandwidth and redundant StackWise cable connections.
Figure 3-2
Example of a Stack with Full Bandwidth Connections
Figure 3-3
shows an example of a stack of Catalyst 3750 switches with
incomplete StackWise cabling connections. This stack provides only half
bandwidth and does not have redundant connections.
Figure 3-3
Example of a Stack with Half Bandwidth Connections
Figure 3-4
and
Figure 3-5
show examples of stacks of Catalyst 3750 switches
with failover conditions. In
Figure 3-4
, theStackWise cable is bad in link B;
therefore, this stack provides only half bandwidth and does not have redundant
connections. In
Figure 3-5
link B is bad; therefore, this stack partitions into two
stacks with switch 1 and switch 3 being stack masters.
